Donald Trumpabruptly ended his friendship with fellow New York billionaire Michael Bloomberg after the former mayor, who is considering a White House bid of his own, snubbed him in the pages of the Financial Times.

“He was a friend of mine. As far as I'm concerned, he's not a friend of mine anymore,” Trump told Fox Business on Thursday, saying that Bloomberg had slighted him with a “nasty shot” in an interview where Bloomberg mused about entering the presidential race because he found “the level of discourse and discussion distressingly banal and an outrage and an insult to the voters.”

“I assume it was taken at me,” a fuming Trump toldStuart Varney. “But when my friends say things like that—assuming it was meant at me—I no longer consider them friends. I knew Michael very well. And he was a friend of mine.”

Rumors of a Bloomberg candidacy first surfaced last month in The New York Times, which reported that he had asked advisers to draw up plans for an independent run if Trump andBernie Sanders were the Republican and Democratic nominees—an outcome that became increasingly plausible after their double-digit victories in the New Hampshire primaries Tuesday. Allies and friends told the paper he was prepared to sink as much as $1 billion of his own fortune into the third-party challenge, news that was immediately heralded by Republican National Committee Chairman Reince Priebus as likely to split the Democratic vote. Trump has also welcomed his one-time golf partner to the race, telling Varney that he “would love to compete against Michael” and that he would inevitably “beat” him.

The relationship between the two New York–based billionaires goes back decades, with Trump praising his “friend’s” business intelligence as the head of a major financial news and media company (“It’s different kinds of business, it’s a very different kind of business”), bragging about their former business deals (one of which involved converting a construction site in the Bronx into a Trump-owned golf course) and hesitating to criticize him when given the chance. In recent days, however, he has appeared wounded by their falling out, saying he does not appreciate Bloomberg Media’s coverage of his candidacy. “I have been treated worse by Bloomberg than I think any other group,” said Trump. “Because of that, I think he’s running.”

"Four Trump allies and one Clinton associate familiar with the exchange said that Clinton encouraged Trump’s efforts to play a larger role in the Republican Party and offered his own views of the political landscape."

"The tone of the call was informal and Clinton never urged Trump to run, the four people said. Rather, they said, Clinton sounded curious about Trump’s moves toward a presidential bid and told Trump that he was striking a chord with frustrated conservatives and was a rising force on the right."

Hillary Clinton, Bill's wife, is the front-runner for the Democratic nomination for president in 2016.

The Clintons have long had ties with the real-estate magnate. As The Post notes, Hillary Clinton attended Trump's wedding in 2005, and the reality-television personality donated money to her past Senate campaigns, though he has also donated to several of his own Republican presidential rivals. He has said those donations were transactional.

The former president has spoken positively of Trump in the past.

In a 2012 interview with CNN, Clinton said he liked Trump, despite the real-estate mogul's controversial campaign to get President Barack Obama to release his birth certificate.

"Donald Trump has been uncommonly nice to Hillary and me. We're all New Yorkers," Clinton said. "I like him. And I love playing golf with him."

Aides to both Bill Clinton and Trump did not comment on record to The Post. Hillary Clinton's campaign also didn't respond to a request for comment.

Bill Clinton had some nice things to say about Donald Trump, the newest Republican presidential candidate, in an interview Wednesday night on The Daily Show. E! Online reports:

"He has been, believe it or not, uncommonly nice to Hillary and me," Clinton replied. "He thought Hillary was a good senator for New York after 9/11 and he has actually, he's one of the many Republicans who supported our foundation before they got the memo."

Republican lawmakers had last month asked the IRS to find out if the Clinton Foundation complied with the terms of its tax-exempt status and the group has said it planned to refile at least three years' worth of tax returns after errors were found in how they reported donations from governments, Reuters had reported.

Trump had invited Bill and Hillary to his wedding to third wife Melania in Palm Beach, Florida in 2005. Bill and Trump had also gone golfing together with fellow famous friends such as former New York City mayors Rudy Giuliani, also an ex-presidential candidate, and Michael Bloomberg, at a tournament at the Trump National Golf Club in Briarcliff Manor, New York in 2008.

Between 2002 and 2006, Trump donated a total of $6,200 to Hillary's campaign for Senate re-election and in 2007 and 2008, he donated $4,600 to her first presidential campaign.

Politicoreports that Trump gave a total of $100,000 to the Clinton Foundation, which has found its financial practices under scrutiny in the run up to the 2016 election, and $25,000 to the national Democrats’ congressional efforts in 2006, when Democrats took over the House and Senate. Donald Trump could say he knows how to pick a winner. In the 2012 election cycle, the last time Trump flirted with a presidential run, the real estate mogul noted “everyone is Democratic” in New York, which doesn’t quite explain the donations to national Democrats. Politico notes Trump has given exclusively to Republican campaigns since 2012.

Trump is polling at an average of 3.6 percent in a field with more than a dozen candidates. Bill Clinton isn’t the only Democrat that welcomed Trump into the race. The Democratic National Committee said “Trump adds some much-needed seriousness that has previously been lacking from the GOP field, and we look forward to hearing more about his ideas for the nation." Careful what you wish for.

1) Trump has favorability ratings that make him unelectable: The American public is very familiar with Donald Trump and people hate his guts. Trump’s current favorable/unfavorable rating is 34/58. Just as a point of comparison, the two biggest landslides in history were against Jimmy Carter (33/58) and Walter Mondale (34/40). Trump is so unpopular with the general electorate that we might as well be running Jared Fogle or Bill Cosby.

2) Trump consistently loses to Hillary Clinton in head-to-head polls:Given that so many people know Trump and already dislike him, it’s hard to understand why anyone thinks he’ll win in November. That’s especially true since the public already knows both him and Hillary Clinton well and he consistently loses to her in head-to-head match-ups.Hillary has 20 wins, 4 losses and 1 tie against Trump over the last 25 polls.Those numbers are more likely to get worse than get better.

3) Huge Republican defections are possible: Trump’s toxic, he’s not a conservative and he has personally insulted an enormous number of people on the Right. There will be more Republicans who won’t vote for him than for any other Republican nominee in recent history. In fact, it wouldn’t be a shock if there are significant numbers of prominent Republicans who back a third party candidate or otherwise try to deliberately undermine his campaign.

4) He won’t be financially competitive in a general election: Hillary Clinton and the Super PACs supporting her will probably spend north of 2.5 billion dollars against Donald Trump. Trump has no Super Pacs and has made not taking money from big donors a centerpiece of his campaign. If you take away the value of his name, Trump would probably have to liquidate his entire fortune to compete financially with Hillary. Even if that were possible, which it’s not, Trump has been very reluctant to spend his money. He even admits that he doesn’t know how he’d fund his campaign in a general election.

5) Trump’s strategy is entirely dependent on the mainstream media:Liberals in the mainstream media have been giving Trump a free ride because they think he’ll be easy to beat in the general election. The day he becomes the nominee, they’ll turn on him just like they did with John McCain and he’ll face hostile treatment in every media venue. The moment that happens, Trump’s core campaign strategy will no longer work.

6) He makes gaffes: He’s the single most gaffe prone candidate in history. He says something dumb enough to end a normal candidate’s campaign every other week. Not only will his gaffes be used against him in a general election, he’ll regularly make more because that’s just what he does. Not only will that hurt his campaign for President, it will help wash out other GOP candidates who will regularly be forced to respond to the latest stupid thing he’s said.

7) He claimed George W. Bush lied about WMDS: Trump is indistinguishable from Michael Moore and Code Pink on the war in Iraq. Trump said Bush was the worst President in history, said he should have been impeached and claimed that he lied about WMDs to trick Americans into going to war.

11) A man as thin skinned and vengeful as Trump can’t be trusted as President: Trump has written whole chapters of books that discuss how important it is to get revenge on people who cross him. If you trust a man who thinks like that with the FBI, DOJ, DHS, our military and the IRS, then you are either foolish or you just assume he won’t go after you and don’t care if he abuses his office to go after other people.

12) He’s a drama queen: One day he’s getting in a fight with Megyn Kelly; the next day he’s saying Carly Fiorina is ugly and the next thing you know, he has a back and forth going with the Pope. Trump’s like a five year old who will pull the cat’s tail, throw a ball through the window or curse in front of company as long it gets people looking at him. Good attention, bad attention, he doesn’t care. The same traits that make Donald Trump great on reality TV would make him temperamentally unfit to be President.

13) Trump is caught up in ongoing fraud trials over “Trump University:” There are two class action suits against Trump in California and the New York Attorney General has also filed suit against Trump over Trump University. One of the trials is scheduled to happen in August. So, right as the presidential campaign goes into full swing, the news will be full of stories about Trump and fraud.

14) Trump has extensive ties to the mob: According to a book written about him, “Throughout his adult life, Donald Trump has done business with major organized-crime figures and performed favors for their associates."

15) Trump was publicly supporting amnesty in 2013: Back when the gang of 8 amnesty bill was being discussed by Congress, Donald Trump who claims he’ll be tougher than anyone on illegal immigration was publicly calling for amnesty for illegal aliens.

16) Trump still supports citizenship for illegal aliens: Despite the fact that Trump is supposed to be tougher than anyone else on immigration, he’s in favor of rewarding many illegal aliens with American citizenship after they touch back in their home countries.

17) Trump doesn’t even make his OWN products in America: Trump claims he’s going to be tough on companies that move jobs overseas, but his own products are made in China and Mexico. Do people really think he’s going to crack down on his own businesses?

18) Trump’s country club in Florida rejects American workers for foreign labor: Donald Trump talks a good game about looking out for American workers, but in practice he has his products made overseas and he hires foreigners over Americans here in the states.

Donald J. Trump’s Mar-a-Lago Club in Palm Beach, Fla., describes itself as “one of the most highly regarded private clubs in the world,” and it is not just the very-well-to-do who want to get in.

Since 2010, nearly 300 United States residents have applied or been referred for jobs as waiters, waitresses, cooks and housekeepers there. But according to federal records, only 17 have been hired.

In all but a handful of cases, Mar-a-Lago sought to fill the jobs with hundreds of foreign guest workers from Romania and other countries.

19) Trump loves Planned Parenthood:Although he claims to be pro-life, Donald Trump has repeatedly praised the baby-killing, baby-part-selling butchers at Planned Parenthood.After being criticized harshly for refusing to cut off funding for the organization, Trump now mixes praise of the organization with unbelievable claims that he will cut off its funding. Even Planned Parenthood doesn’t believe Trump will hurt them because the organization’s CEO Cecile Richards said she appreciated Trump’s“kind words.”20) Trump can’t be trusted to pick a Supreme Court Justice: A non-conservative who has kind words for Planned Parenthood and who thought his radical, pro-abortion sister would make a great justice if she wasn’t related to him is not someone you want picking a replacement for Antonin Scalia.

21) Donald Trump is largely indistinguishable from Bernie Sanders on health care: If Trump were to somehow become President, Republicans would have to root for Obamacare to stay in place because what Trump wants to do is worse. Trump has been advocating government-controlled single payer health care for over 15 years. Trump is so ignorant about health care that he’s unable to discuss the subject intelligently, but even as he denies that he still wants single payer health care, he says that everyone is going to be covered and the government will pay for it. If you thought there couldn’t possibly be a bigger liar on health care than Barack Obama, then meet Donald Trump.

22) Eminent domain: Not only is Donald Trump in favor of having the government use the power of eminent domain to take property from private owners so it can be given to fatcats like him, he tried to use eminent domain to take a widow’s home away from her so it could be used as a limo parking lot. If you think Donald Trump is for the little guy, you’re a sucker.

23) Trump is making it clear he will undermine Israel: Here’s Trump on the conflict between the pro-American Israelis and the anti-American, genocidal, pro-terrorist Palestinians, "I don't want to get into it for a different reason, Joe, because if I do win, there has to be a certain amount of surprise, unpredictability. Let me be sort of a neutral guy, let's see what -- I'm going to give it a shot. It would be so great." Since when do conservatives back a President who doesn’t support Israel?

24) Trump isn’t a conservative and has no consistent ideological values: Trump has switched political parties 5 times in his life, was endorsing Democrats three years ago and his positions on the issues sometimes change week to week.

25) Trump was endorsing Democrats just three years ago: Michael Bloomberg is the foremost advocate of gun control in the United States and Bill De Blasio is an open Marxist. Yet, here’s what Trump was saying about them three years ago.

26) He’s a Clinton Foundation donor: As was noted in the debate on Thursday night, it would be hard for Trump to make an issue of all the sleazy things that the Clinton Foundation was doing when he was one of its donors.

27) Trump has publicly talked about how wonderful Hillary Clinton is on multiple occasions:

"I know Hillary andI think she’d make a great president or vice-president." – 2008

Not only would these quotes help Hillary in an election, Trump’s shtick is always that he may have no idea what he’s talking about, but he’ll choose good people.

Like Hillary?

28) He has the thumbs up from Jimmy Carter: “I think I would choose Trump, which may surprise some of you. The reason is, Trump has proven already he’s completely malleable. I don’t think he has any fixed (positions) he’d go the White House and fight for. On the other hand, Ted Cruz is not malleable. He has far-right wing policies he’d pursue if he became president.” – Jimmy Carter on whom he’d like to see as the Republican nominee

29) Donald Trump has been a big supporter of the Democrat Party:Among the many, manyDemocrats Donald Trump has donated to are Hillary Clinton, Rahm Emanuel, Anthony Weiner, Nancy Pelosi, Harry Reid and Walter Mondale. Trump even donated the maximum to Jimmy Carter when he ran against Ronald Reagan.

30) He doesn’t know anything about policy: I don’t know if it’s because he’s lazy, not interested in policy or just because he’s old and has difficulty learning new things, but Trump doesn’t know anything more than the most basic facts about any issue. He literally does not understand immigration, healthcare or foreign policy on anything more than the most superficial level. Trump would never hire a guy who doesn’t know what he is talking about to run one of his construction sites; so why should Americans hire a guy who’s completely ignorant of policy to be President?

31) Trump is a too old to be running for President: If he somehow wins, Donald Trump will be 70 years old when he takes office. That would make him the oldest man ever to be elected to the White House for the first time.

32) Trump has many failed business ventures: Trump gives people the impression that he always wins. Certainly he has had a lot of success, but he also failed over and over again in ventures he knows little about just like he will if he’s the GOP’s nominee. It will be one more failed business venture like Trump steaks, Trump Vodka, Trump the Game, Trump Magazine, Trump Mortgage, Trump Airlines, Trump University, Trump Casinos and the New Jersey Generals.

33) Trump mocked prisoners of war: I don’t much care for John McCain, but Trump didn’t just insult McCain, he mocked every American prisoner of war when he said,“(John McCain is) not a war hero…. He’s a war hero because he was captured.I like people that weren’t captured.” There were a lot of American war heroes who served honorably and were captured. They shouldn’t be laughed at by a man who never even served in the military.

34) Donald Trump makes fun of the handicapped: What sort of man mocks people for being handicapped? Trump has done it at least twice. He made fun of Charles Krauthammer, who’s paralyzed, by saying, "I get called by a guy thatcan't buy a pair of pants, I get called names?" Trump also mocked the appearance of a New York Times reporter with a congenital joint condition. You’d be ashamed of your own child if he behaved this way; so how can you vote for a man like this?

35) Donald Trump would be the first President to have made money off of a strip club:Are you really going to be proud to tell your kids that you’re backing a guy who made money off of casinos and a strip club for President?

36) Trump cheated on his wife: Not only did cheat Trump on his wife, heBRAGGED about sleeping with married women in one of his books.

37) He’s made creepy comments about dating his daughter: Sorry, but this is just a gross, weird and completely inappropriate comment to make about your own child, “I don’t think Ivanka would do that [pose for Playboy], although she does have a very nice figure. I’ve said if Ivanka weren't my daughter, perhaps I'd be dating her.” Incidentally, he’s said things like this more than once.

40) Last but not least, Trump’s an even more perfect example of narcissistic personality disorder than Barack Obama: I’ll just leave this description here so you can make your own judgment.

An all-pervasive pattern of grandiosity (in fantasy or behavior), need for admiration or adulation and lack of empathy, usually beginning by early adulthood and present in various contexts. Five (or more) of the following criteria must be met:

Feels grandiose and self-important (e.g., exaggerates achievements and talents to the point of lying, demands to be recognized as superior without commensurate achievements)
